<p><P>PROBLEM TO BE SOLVED: To eliminate a level difference completely by fitting a block structure to any existing level differences having various dimensional differences. <P>SOLUTION: The block structure includes a plurality of block bodies having different heights. Each of the block bodies is formed to be a triangle in cross section or to be a triangular pyramid in which the upper surface is formed to be a tapered surface and the bottom surface is in contact with a floor surface. A front end of each of the block bodies is connected to the other block body in series in an integrating manner and a slope eliminating the level difference is formed by the continuation of the upper surfaces of the block bodies. The whole structure is made to be the triangular pyramid in which a plurality of cutting lines along the height direction are formed at predetermined distances from the rear end, and the block structure is used after cutting off the rear end part according to the height of the level difference which is to be eliminated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
